Stocks that are making large-percentage moves are favorites among short-term traders because they can jump into these names and try to capture some of that massive volatility. Stocks that are making big-percentage moves either up or down are usually in play because their sector is becoming attractive or they have a major fundamental catalyst such as a recent earnings release. Sometimes stocks making big % moves have been hit with an analyst upgrade or an analyst upgrade.

Regardless of the reason behind it, when a stock makes a large-percentage move, it is often just the start of a new major trend -- a trend that can lead to huge profits. If you time the trade correctly and combine a number of technical indicators with fundamental trends, discipline and sound money management, you will be well on your way to investment success.

From a technical standpoint, NBG will trigger a major breakout trade if the stock can manage to move above $2.10 on high volume. A move over $2.10 will bring a large gap down into play from $2.40. That gap could easily get filled back to $2.40 if $2.10 is taken out with volume.

Traders should watch for a high-volume move over $2.10 that is near or above 687,458 shares.

U.S. Airways Group

U.S. Airways Group (LCC), through its subsidiaries, provides air transportation for passengers and cargo. This stock is trading up 5.5% at $5.48 in recent trading.

Today’s Range: $5.25-$5.50

52-Week Range: $3.96-$11.56

Volume: 3.6 million

Three-Month Average Volume: 6.9 million

The airline sector is catching a bid today after Delta Air Lines (DAL) updated its guidance ahead of an investor meeting. The airline said it expects to earn $800 million in fiscal 2011.

From a technical standpoint, LCC has started to move back above its 50-day moving average of $5.26 on decent volume. Market players should now watch for the next upside trade to trigger if LCC can manage to breakout above some near-term overhead resistance levels.

Watch for a move above $5.81 and then $6.08 on high volume to trigger more upside for LCC. Watch for volume that registers near or above 6.9 million shares if those levels get taken out in the near future.

TranS1 (TSON) is a medical device company focused on designing, developing and marketing products that implement its minimally invasive surgical approach to treat degenerative disc disease and instability affecting the lower lumbar region of the spine. This stock is trading up 20% at $2.15 in recent trading.

Today’s Range: $1.95-$2.39

52-Week Range: $1.39-$5.42

Volume: 760,000

Three-Month Average Volume: 163,752

Shares of TSON are soaring higher today after the company announced that Palmetto GBA has removed its non-coverage policy for AxiaLIF effective Jan. 1, 2012.

From a technical standpoint, TSON is gapping higher back above its 50-day moving average of $1.95 on monster volume. What’s interesting about this move is that the stock hit some stiff resistance once it got close to its gap down day’s high price from October.

I would not look to get long TSON again until the stock moves back above that gap down day high of just over $2.60 on high volume. Traders should look for volume that’s near or above 163,752 shares on any future move over $2.60 to trigger the next long biased trading opportunity.

RiT Technologies

RiT Technologies (RITT) is a provider of intelligent solutions for infrastructure management, asset management, environment and security, and network utilization. This stock is trading up 20% at $4.92 in recent trading.

Today’s Range: $4.73-$5.90

52-Week Range: $1.10-$13.45

Volume: 466,000

Three-Month Average Volume: 21,719

Shares of RITT are soaring today after the company said it will convert an outstanding loan of about $3.2 million into over 636,000 ordinary shares at an average price of $5.09 per share.

From a technical standpoint, RIT broke out above two key levels earlier in the trading session when the stock cleared its 200-day moving average of $5.01 and some past overhead resistance at $5.38. That said, the stock has now failed to hold above those levels with shares trading at $4.92 at last check.

Traders should avoid this stock form the long side if it closes near the daily low of $4.65 and if it closes below the 200-day.

From a technical standpoint, AMPE is bouncing big off of some previous support levels near $5 to $4.62. This bounce is coming on above-average volume, which is bullish. That said, the stock is still trending below both its 50-day and 200-day moving averages, which is longer-term bearish.

I wouldn’t look to play this stock from the long side until it can manage to move back above its 200-day moving average of $6.62 on heavy volume.

RealD

RealD (RLD) is a global licensor of 3D technologies. This stock is trading up 2.7% to $8.84 in recent trading.

Today’s Range: $8.25-$8.86

52-Week Range: $8.42-$35.60

Volume: 414,000

Three-Month Average Volume: 605,181

From a technical standpoint, RLD is bouncing today right off of some previous support of $8.55 today on solid volume. This action in such a weak market could be signaling a bottom in RLD as long as the stock doesn’t trade back below $8.55 on heavy volume.

Market players should now look for RLD to make a run at its 50-day moving average of $10.02, or possibly much higher if this near-term bottom holds.
